John Murray Wighton (Generation 6) was the first member of the Meigle line to live in Glasgow. John Murray worked in the Scottish Prison service and had an assignment at Barlinnie Prison. We're not sure exactly when his service at Barlinnie began, but we do know that he was in Milngavie, a residential community 7 miles north-west of Glasgow in 1908 when his daughter Ella Burns Wighton was buried in the town. He continued to work at Barlinnie until 1919 when he retired to the Isle of Mann.
That would put John Murray Wighton in Glasgow in 1916 when his son, Harry Wighton, arrived with his wife (Miriam) and his two children (Ella and John) by steamship S.S. Pretorian from Montreal, Canada. Harry and family had been living in Vancouver, BC when the Great War began. Harry had emigrated to Scotland some years before and decided to return to provide service to his country during the war. Harry worked in a Glasgow munitions factory - one of which is shown in the picture below. A third child, James, was born in Glasgow on December 31, 1916. The family returned to Canada via the United States in October, 1918.
